Privacy policy
Last updated: 8 October 2026
Hopadoo is a movement game for kids. We built it to collect as little as possible. This policy covers the game (hopadoo.app) and this website (hopadoo.com).
Hopadoo ("we", "us"), based in India, runs both and is the controller of the personal data described here. Privacy questions: hello@hopadoo.com.
The game and the camera
- The camera video is processed entirely on your device, in the browser. We never receive video, photos, body positions or any other camera data.
- The game has no accounts, ads or tracking. We count visits with Cloudflare Web Analytics (see below).
- The game counts how often each game is opened, played and started a round, how often it shows an error screen, and whether it's a first or returning visit, as daily totals per game, so we know whether Hopadoo works for families. It sends no information about you or your device, and we keep only those totals.
- We don't knowingly collect any personal information from children.
- The game downloads its own files and a pose-detection model. Those requests don't include anything about you.
Unlocking the game
If you buy the Family Unlock, the game sends your license key and a random device ID to our server once, to check the key and count devices. We store a scrambled (hashed) copy of the key, Paddle's ID for the purchase, the random device IDs and whether it's been refunded. We don't store names or email addresses on that server. Right after you pay, the game uses the purchase ID instead of the key, so the laptop you bought on unlocks straight away. If you ask us to resend your unlock, we use the email address you type only to look up your purchase with Paddle, and we don't keep it.
Buying through Paddle
Purchases are handled by Paddle.com, our reseller and Merchant of Record. Paddle collects your name, email, payment and billing details to process the order, under Paddle's privacy policy. Paddle shares your email address and order details with us so we can send your unlock link and help if something goes wrong. We never see your card details.
Emails
We send the unlock email you need after a purchase, through Cloudflare's email service. If you sign up for news, we send occasional updates, and every email has an unsubscribe link. We use Zoho to send those and to store your address. Zoho's servers are in the United States.
This website
We count visits to this site and the game with Cloudflare Web Analytics, which uses no cookies and, Cloudflare says, collects no personal data: just pages opened, country, browser and where the visit came from. The website, the game and our license server are hosted on Cloudflare, which processes basic request data such as IP addresses to deliver and protect them.
Why we use it
To sell you the Family Unlock and make it work (performing our contract with you), to answer your emails and stop fraud and abuse (our legitimate interest in running a safe service), to send news only if you asked for it (consent), and to keep records the law requires (legal obligation).
Who we share it with
Paddle, to sell and support your purchase; Cloudflare, which hosts the site, the game and the license server, counts visits and sends unlock emails; Zoho, for our email; professional advisers where needed; and authorities where the law requires it. Some of these process data outside your country, including in the United States.
How long we keep it
License records (the hashed key, purchase ID, device IDs and refund status) are kept for as long as the Family Unlock works, so your devices stay unlocked. Restore requests leave only a scrambled rate-limit counter, deleted after an hour. Emails you send us are kept while we need them to help you. Paddle keeps order records as tax law requires. When we no longer need data, we delete or anonymise it.
Keeping it safe
Everything travels over HTTPS, license keys are stored only as hashes, and access to our hosting, payment and email accounts is limited to us.
Your rights
You can ask us what we hold about you, to correct it, or to delete it. Email hello@hopadoo.com. If you're in the EU or UK, you can also complain to your data protection authority.
